Struggly is a high-impact K-6 supplemental math curriculum that builds number sense, confidence, curiosity, and a love of math.

Seeing is understanding

Multiplication

Understanding multiplication as structure

Students see how factors form products by connecting equal groups, skip counting, and visual number patterns—building a strong foundation for multiplication.

Our approach
Multiplication Facts

Connecting representations for fact fluency

Students build fact fluency by sorting cards that show products in multiple ways—expressions, arrays, dice, and models—connecting understanding to recall.

Our approach
Equations

Solving for unknowns in equations

Students reason about totals and unknown values using visuals, connecting their thinking to equations and building understanding of multi-step solving.

Our approach
skip-counting

From skip-counting to multiplication

Connects repeated addition, skip counting, multiplication and division. Build the multiplication table from scratch to understand and see arrays.

Our approach
Addition with Regrouping

Understanding place value in regrouping

Students visualize regrouping in multi-digit addition, connecting place value to trading units across ones, tens, and hundreds.

"Many of the students said that Struggly helps "grow their brain!" Thank you for helping to increase our first graders' curiosity and interest in math this year!"
Lisa Brown
First Grade Teacher at Sandburg Elementary School
“My students using Struggly all upped their math score by one grade level on the recent diagnostic that was given. This is the first year I had my whole class improve one entire grade level or more”
Christopher Dewhirst
